A trip around the world on the Ural

I recently found a post about the crazy journey of several Germans,their route passed through Germany-Poland-Russia.

They want to get to the Bering Strait, and ride through Alaska and Canada to finish in New York.

They are traveling on the Ural sidecar.

20,000 km to Magadan they already passed.
During the winter they decided to paddle down the Kolyma. Only 1600 km.

The US company helped with the pontoons that were used in the construction of a prototype for the "Kolyma Challenge".The size of 2x5 m.

But, spent all the money. The guys started a company for crowdfunding.
